Rebirth 2010: I add some points to be a boss

Chapter 232 Mass production of 28nm chips, coveting Huayao's chip design

The next day.

The summer cicadas chirped softly, and the heat was transpiring.

Chen Heyu opened his eyes again, and lying in his arms was a cute little girl who bullied Shuang Shengxue, with long hair like a waterfall and an exquisite body.

Lips are plump and shiny, like a watery jelly.

Lifting a corner of the blanket, he walked out of the room lightly and went to the bathroom to wash up. His back was strong and straight, benefiting from years of exercise and some optimization.

There is no fat on the whole body, and the muscles are sharp and angular.

Back in the house, the little girl was still soundly asleep, he picked up his phone to check the time, stepped forward and shook her fragrant shoulders.

"If you don't get up, you'll be late for work."

Chen Heyu reminded.

"I'm the boss, who dares to check my attendance, hehe."

Luo Wenwen said in a daze.

"Did you forget that the investor is the father of the funder, and dare to be lazy in front of me!"

Chen Heyu lowered his head, leaned into her ear and said.

"It's all your fault. You have been tossing me for so long, and now I can't get up at all, what should I do?"

Luo Wenwen opened her eyes, her slender eyelashes trembling slightly, and said slowly.

I was weak all over, and my thighs were sore.

"Um, then rest well at home, I'm going to Shanhai Weidian in the morning, I can't stay with you at home.

After a while, I asked Aunt Liu to prepare breakfast and remember to get up to eat. "

Chen Heyu pinched her little face and said with a smile.

"Eat, eat, eat! I know, you idiot, run away after playing!"

Luo Wenwen snorted tenderly.

"I'll teach you a lesson tonight."

Chen Heyu smiled slightly, walked into the cloakroom, changed into a suit, and when he reached the first floor, Lao Mo had already been waiting outside the door for a long time.

"Go to Shanhai Microelectronics."

"Okay, it's about 10 minutes by car."

Ding Mo replied immediately.

"Yo? Today is a little different? Going out on a date?"

Chen Heyu teased, and found that Lao Mo's words began to increase.

Lao Mo's face turned red in an instant, and he quickly argued: "No, no."

"Really? If you want to marry a girl in Shanghai, you must have at least one apartment. Is the down payment enough?"

Chen Heyu asked.

"There is still a shortfall of 30, and two more years will be enough, and I still have an old house in Yancheng."

Ding Mo replied subconsciously.

"Oh? I'm thinking about buying a house. It seems that the relationship is progressing very quickly."

Chen Heyu said with a smile, looking at the cramped old Mo.

"Boss, I..."

What else did Ding Mo want to explain.

"In two years, I'm afraid that the house price will double, and you haven't earned your 30 yuan. I'll ask the accountant to charge your account later, and pay attention to check."

Chen Heyu smiled, and said directly.

"thank you boss."

Ding Mo thought for a while, but he didn't refuse. It was too slow to make money from wages and stocks. He was really struggling, worried that he would not be able to catch up with the rising speed of house prices.

Feeling moved in his heart, the boss's care for him was deeply remembered by him.

"It's not that you don't want to pay it back? What are you happy about?"

Chen Heyu joked.

……

a while.

Coming to the Guanglan Road Software Park again, the signboard of Zigang Electronics has been replaced by Shanhai Microelectronics, and it has a new life.

The faces of the staff who come and go are full of pride.

Everyone knows that this morning, the company will hold a 28nm chip production kick-off meeting. If it is a complete success, it will become the first semiconductor company in China to achieve mass production of mid-to-high-end chips.

This means a large number of orders, a rapidly expanding market value, and huge bonuses!

It is closely related to everyone in the company. After Chen Heyu took power, he sorted out and reshaped the organizational structure of Shanhai Microelectronics, and those who stayed basically received a share of dividends.

At the end of each year, bonuses will be distributed according to the net profit, which greatly improves the enthusiasm of employees for R&D and production.

"Mr. Chen, the chip mask template is finished, we can visit the lithography machine workshop first."

He Tingbo greeted him.

"boss."

Wang Maosong greeted.

"According to what you said, how much can the estimated yield rate be controlled?"

Chen Heyu walked ahead and asked sideways.

"Combined with laboratory data, it is roughly judged to be above 80%."

He Tingbo is most familiar with the core technical parameters, and said without hesitation.

"It's a little lower. If the 100 NXT 1950i DUV lithography machines arrive, is there still room for decline?"

Chen Heyu asked.

The reported loss rate of 20% is indeed a bit high, but there is no way. Most of the lithography machines of Shanhai Microelectronics are old facilities. It is considered good to be able to burn chips normally, and I dare not expect too much.

Compared with the 70% yield rate of domestic lithography machines, this value is barely acceptable.

"It is estimated that 90% can be achieved!"

He Tingbo replied.

Chip giants such as Intel and Percom basically use the NXT 1950i DUV lithography machine, and the yield rate is stable at 90%.

"Well, I see."

Chen Heyu nodded and replied, in the era when EUV lithography machines were not yet born, it was not easy to achieve a 90% yield rate.

It will take until 2018 when EUV lithography machines are widely used to meet the increasingly sophisticated semiconductor manufacturing needs and greatly improve the yield rate.

This is because the EUV lithography machine uses an extreme ultraviolet light source, while the DUV lithography machine uses a deep ultraviolet light source.

The wavelength of EUV light source is about 13.5 nanometers, which is much shorter than that of DUV light source, which can achieve finer resolution and smaller process size, and shorter wavelength can produce more delicate images.

But it is not without disadvantages. Manufacturing and maintenance costs are high. The stability of the light source and lens manufacturing are still difficult problems. It will be wishful thinking to apply it to the semiconductor industry within three to five years.

A group of people came to the manufacturing department and put on dust-free clothes, anti-static shoes, hats and headgear, and protective masks to deal with risks such as chemical spraying and dust flying that may exist in the workshop.

Everyone stood aside, following Chen Heyu's gestures.

An operator came out and immediately took out an 8-inch wafer. After careful observation, he made sure that there were no impurities and pollutants on the surface, and then took out a transparent negative with circuit patterns, which is the template of the photomask, and placed it carefully on the on the lithography machine.

"continue."

Chen Heyu is no stranger to these operations. After entering the Fan-Out packaging technology into the system, he has decades of experience in chip packaging and testing in his mind. It can be seen that the operator's movements are very skilled.

At this point in the process, the operator uses a spin coater to coat the photoresist on the wafer, because the photoresist is photosensitive and can change its chemical properties after exposure to ultraviolet light to form complex circuit patterns.

The wafer is then soaked in a developer, which removes the photoresist that was not exposed to UV light, leaving only the exposed patterned areas, a step that transfers the circuit pattern to the surface of the silicon wafer.

After completion, hundreds of rectangular chips appear densely packed on a wafer, covered with hundreds of millions of invisible transistors.

The etching process is then used to remove the material not protected by the photolithographic pattern, thereby revealing the various structures and circuits of the chip.

The chemical vapor deposition method is then used to fill the wafer with materials, such as metals, insulators or conductors, to form different circuit components.

Finally, cleaning and inspection processes remove residues and detect potential defects, which help ensure chip quality and reliability.

This step requires a large amount of pure water, especially in large-scale production, so Shanhai Microelectronics is equipped with huge water treatment facilities to meet production needs and ensure a stable supply on the production line.

"This is the graphics processing unit (GPU) for the rice tablet, and the design is provided by Songguo Technology."

He Tingbo explained next to him.

I saw the operator setting metal cables on the chip to connect various circuit components.

The design and production of metal cables determine the layout and current transmission capacity of the chip, and then use three-dimensional packaging technology to package the chip in ceramic materials, and a final product is completed.

"Mr. Chen, do you want to verify the function and performance of the chip?"

He Tingbo asked.

"Naturally, you can operate it, and let me see the level of the first generation of semiconductor research engineers."

Chen Heyu said with a smile.

"no problem."

He Tingbo was born as a researcher and participated in the research and development of the first generation of lithography machines. He is an expert in the fields of software and hardware.

Go ahead and grab a chip, and use oscilloscopes, emulators, high-frequency testing and power analysis equipment to start measuring the core parameters of the chip.

While operating, record the experimental data.

"Compared with 40nm chips, this new product has obvious improvements in processing speed, power consumption, integration, power consumption and performance balance, and can provide better performance and efficiency.

The overall yield rate is 81%, but this is a floating value. Perhaps the yield rate of the next wafer is only 79%, or even 78%. "

He Tingbo concluded.

"The wafer processing plant in Jinling can be started. In addition, the public relations department and marketing department can get ready to hold a media conference."

Chen Heyu said with a smile.

More than 100 billion funds have been poured in one after another, and finally there are research results. In 2024, 28nm chips are not even needed, and can only be used in the low-end application market.

But this was in 2015. Chips with this process technology were enough for Shanhai Microelectronics to occupy the mid-to-high-end market. For example, the Snapdragon 805 chip of Haotongjia is a processor produced by using a 28-nanometer process.

"Shall we do OEM for MVIDIA first?"

Wang Maosong asked.

"Otherwise? Let the company shut down? At present, we don't have the research and development capabilities of mobile phones and computer chips. Let's survive first."

Chen Heyu replied.

The benefits of investing in MVIDIA are reflected, at least it can solve the survival problem in the early stage.

"I made an appointment with Mr. Yu from Huayao to come to Shanghai to discuss and take charge of hosting the meeting. First, we will open up the domestic market."

Chen Heyu confessed.

The next day, the news media began to spread the propaganda overwhelmingly, and domestic self-developed chips officially entered the era of 28nm chips.

"Shanhai Microelectronics develops 28nm chips to create a mature technology leader, and say no to Bay Semiconductor!"

"MVIDIA throws an olive branch and sends a purchase order of 6 million yuan!"

"The King of Shanhai Microelectronics is back! The new 28nm chip has achieved mass production and is expected to replace GSMC!"

"Mr. Chen, congratulations. The old leader asked me to tell you, just go ahead and do it. As long as you can break through the 14nm technology blockade, you will be able to achieve what you want."

Secretary Liu deliberately turned on the phone to congratulate her.

"Thank you, Mi Liu."

Chen Heyu smiled lightly.

He is not reconciled to being a pure foundry, burying himself in the production of silicon wafers for Intel, Haotong, and MVIDIA, and in the end most of the money was taken away by foreigners.

Half of the world's top chip engineers are Chinese R&D personnel. This shows that as long as the equipment is well-equipped and there is a stable R&D atmosphere, it is absolutely possible to produce more advanced chip technology on the soil of China.

What Chen Heyu has to do is to create a good and superior environment to attract these talents.

Huayao Haisi has been deeply involved in the field of mobile phone chip research and development for many years, and there is no shortage of chip design solutions. Shanhai Microelectronics can fully use the technology accumulation of the other party to gain a glimpse of the mystery of mobile phone chips.

And this first step is to win the production and processing order of Huayao's self-developed chip and obtain the overall chip architecture of the other party, so as to achieve a good balance between the processor core, memory structure, graphics processing unit and signal processor.

……

"Boss, Shanhai Microelectronics has achieved mass production of 28-nanometer chips, and the yield rate is about 80%. It is said that the president of Intel Dahua District intends to purchase some orders."

A sales vice president of Huaxin International is reporting to the boss.

"What do the people below do? It's been so long, and I have no clue at all, and let a small company go ahead of us?

They are shameless, but I still have shame! "

Gao Lexian cursed loudly.

"It's still an old problem, and the packaging technology can't solve it, but the photolithography process has reached the standard, and this last step is missing."

explained the technical president.

"Let's speed up the time. If we can't solve it, we will be in an embarrassing situation. When the other party increases production, not only Intel will be tempted, but Picktone, Pertone, and Texas Instruments will definitely come to seek cooperation."

Gao Lexian felt a headache. Once this hole is opened, it will be even more difficult for Huaxin International to regain the market in the future.
